Kanga - Wooden comb for combing the hair is the symbol closely connected with Sikhee.It is use is for maintenance of the Kesh. The keshas are combed daily with the Kanga.The spiritual significance is regular daily naam simran.
The message of Kanga is to grow in Sikhee with a regular effort.
The Guruji’s advice to the Sikh is
Only that can be known as a Sikh of the True Guru,who rises in the early morning hours and meditates on Har Naam.
The effort is to arise early in the morning, take a bathe, and cleanse himself (of false ego) in the pool of nectar(through simran meditation).
As are the Instructions of the Guru (Gurbani) , with the Jap is of Har, Har ( the repeated assertion of Har (the God in the mind through Gurumantra Waheguru) all sins, misdeeds and negativity is erased ( the Godly qualities then dominate) .
Then, at the rising of the sun, the Gurbani is sung;and whether sitting down or standing up, meditation on Har Naam (simran).
One who meditates on my (guru’s advice) Lord, Har, Har, with every breath and every morsel of food that GurSikh becomes pleasing to the Guru's Mind.
The Guru’s advice for regular daily effort towards Naam Simran is repeatedly stated in Gurbani . Here some lines from SGGSji.
O my mind, give up all these (mind created) efforts (that are not work in your life) . As the Perfect Guru says dwell each day, and develop love with the one Lord pervading as Oneness 1
Continually, continuously, remember the Merciful Lord.
Never forget HIM (your origin ) from your mind.
The continous and regular Simran ( reciting of Gurbani with feeling and remembrance with jap of Gurumantra – Waheguru) is advocated by the Guruji so that the Sikh’s state of mind is lifted from being attached with lower worldly emotions to higher feelings of Love , appreciation , gratitude , cooperation , peace, joy etc. Also the Sikh then rises above thre false ego identification (haume) and reaches the the state of being which Gurbani calls ‘Jyote Swarop’.
A regular continous action is required so that the state of being ‘Jyote Swarop’ is achieved by the Sikh through simran.
Guruji says that :
O my mind, you are the embodiment of the Divine Light - recognize your own origin. O my mind, the Dear Lord is ever with you; through the Guru's Teachings, enjoy the state of Anand.
The Kanga ever reminds us to be regular in our effort in Simran. So a buildup of a relationship with this symbol chosen and graced by the Guru we get the strength and resolve to make daily and regulay simran a part of our life.
